Preparation of x-ray attenuating nanocomposite based on polythiophene and Cdº nanoparticles

Nanocomposites of conducting polythiophene and Cdº nanoparticles has been synthesized via in situ polymerization. Cdº nanoparticles were synthesized by Schlenk techniques. During the syntheses, we used anhydrous and without oxygen material and solvents. Polythiophene (PTh) and Cdo nanocomposite was synthesized by cationic surfactant assisted dilute polymerization method using FeCl3 as an oxidant. Anhydrous FeCl3 as an initiator and DBSA as a doped agent were used for nanocomposite preparation.. The products were characterized by X-ray powder diffraction (XRD), TEM and four-wire-technique respectively. Afterward X-ray interaction parameters such as linear attenuation coefficient, attenuation percentage, half value thickness and mean free path were examined, in similar situation. Also, in order to determine the effect of radiation beam on destroying the polymer chains, we measured the conductivity of samples before and after photon interaction and result proven that conductivity of remain unabated
